Bitcoin’s popularity has undeniably been its number one advantage over the numerous other cryptocurrencies. By gaining a large number of adopters and users, Bitcoin has achieved a network effect that attracts even more users. Users who would otherwise be more apprehensive investing in a relatively unknown and unproven digital currency are reassured by Bitcoin’s performance over time, its growing community, and the fact that people they know are adopting cryptos.
You’ll need a Bitcoin wallet in which to keep your mined Bitcoins. Once you have a wallet, make sure to get your wallet address. It will be a long sequence of letters and numbers. Each wallet has a different way to get the public Bitcoin address, but most wallets are pretty straightforward about it. Notice that you’ll need your PUBLIC Bitcoin address and not your private key (which is like the secret password for your wallet).
A mining pool sets a difficulty level between 1 and the currency’s difficulty. If a miner returns a block which scores a difficulty level between the pool’s difficulty level and the currency’s difficulty level, the block is recorded as a ‘share’. There is no use whatsoever for these share blocks, but they are recorded as proof of work to show that miners are trying to solve blocks. They also indicate how much processing power they are contributing to the pool the better the hardware, the more shares are generated.

Behind the scenes, the Bitcoin network is sharing a massive public ledger called the "block chain". This ledger contains every transaction ever processed which enables a user's computer to verify the validity of each transaction. The authenticity of each transaction is protected by digital signatures corresponding to the sending addresses therefore allowing all users to have full control over sending bitcoins.

The price of bitcoins has gone through cycles of appreciation and depreciation referred to by some as bubbles and busts.[155] In 2011, the value of one bitcoin rapidly rose from about US$0.30 to US$32 before returning to US$2.[156] In the latter half of 2012 and during the 2012–13 Cypriot financial crisis, the bitcoin price began to rise,[157] reaching a high of US$266 on 10 April 2013, before crashing to around US$50.[158] On 29 November 2013, the cost of one bitcoin rose to a peak of US$1,242.[159] In 2014, the price fell sharply, and as of April remained depressed at little more than half 2013 prices. As of August 2014 it was under US$600.[160] During their time as bitcoin developers, Gavin Andresen[161] and Mike Hearn[162] warned that bubbles may occur.

Transactions are defined using a Forth-like scripting language.[3]:ch. 5 Transactions consist of one or more inputs and one or more outputs. When a user sends bitcoins, the user designates each address and the amount of bitcoin being sent to that address in an output. To prevent double spending, each input must refer to a previous unspent output in the blockchain.[67] The use of multiple inputs corresponds to the use of multiple coins in a cash transaction. Since transactions can have multiple outputs, users can send bitcoins to multiple recipients in one transaction. As in a cash transaction, the sum of inputs (coins used to pay) can exceed the intended sum of payments. In such a case, an additional output is used, returning the change back to the payer.[67] Any input satoshis not accounted for in the transaction outputs become the transaction fee.[67]
